New spell idea: Repulsion - keep troops away from parts of a base you don't like!
Name: Repulsion
Training cost: 15-20,000
Targets: All friendly troops
Effect type: When dropped, creates a circle that all your troops will avoid - all units deployed will path around the spell's circumference, selecting the nearest building or defense that isn't within the circles circumference. Any troops inside the circle when it's deployed will immediately path outside the circle, selecting a new target outside as well.
Use the spell to keep troops away from troublesome parts of the base (ie - deploy on an air def, to have dragons avoid the AD's firing range; deploy on a mortar to have troops stay outside the mortars range. Deploy on a bases right side to keep troops away from that side; deploy on builders huts in the corner so your troops focus on the base instead of outlier buildings)
Damage: none
Duration: 5-10 seconds at level 1, depending on balancing; new levels will increase it's duration
Training time: 30 min
Description: When deployed, creates a ring that none of your troops will enter; any buildings inside will not be selected for targeting, even by ranged units. Use to keep troops away from parts of a base you don't want them to go near!
Research: Each level increases either the diameter of the spell's range and/or it's duration
Lab Level: Level 6 - this should be a spell for TH8's and above, since TH8's currently don't have any new spells
